We get found by Indian people all the time. Have no idea how, but Hi...how are ya? (I'm fluent in Indian English. I've been a fan of Bollywood for years. Also a member of numerous British car websites where "lost in translation" happens a lot. I can help Australian, South African and Indian people with automotive issues...as terminology changes)
Yamaha does not allow us(being we are an American site) to view either of those two Pre-Package systems. We can find them where sold(there is more than one Indian internet sales site), but they are lacking in factual details we can use.
YPAO is worth it. I'm not among the bastian of people who think room EQ are absolutely necessary though. Not sure if the YPAO in question includes "bass trim" (that is a Yamaha feature included with some Yamaha YPAO equipped AVR) or not.
If the 298 does in fact include bass trim...then yes...wholeheartedly...spend the extra money.
